Applications Information
The voltage across the current sense resistor (R
pin. If the voltage across R
timer activates.
A small ceramic bypass capacitor close to this pin is recommended to suppress
transients which occur when the load current is switched off.
An external resistor divider from the system input voltage sets the under-voltage
turn-on threshold. An internal 21 µA current source provides hysteresis. The
enable threshold at the pin is 2.5V. This pin can also be used for remote shutdown
control.
An external resistor divider from the system input voltage sets the over-voltage
turn-off threshold. An internal 21 µA current source provides hysteresis. The
disable threshold at the pin is 2.5V.
An external capacitor connected to this pin sets the insertion time delay and the
Fault Timeout Period. The capacitor also sets the restart timing of the LM5069-2.
An external resistor connected to this pin, in conjunction with the current sense
resistor (R
pass MOSFET.
An open drain output. When the external MOSFET V
the PGD indicator is active (high). When the external MOSFET V
above 2.5V the PGD indicator switches low.
Connect to the output rail (external MOSFET source). Internally used to determine
the MOSFET V
Connect to the external MOSFET’s gate. This pin's voltage is typically 12V above
the OUT pin when enabled.
